Photo Diary: Ai Weiwei at Mary Boone in Chelsea.

I know these are porcelain and that they’re hand-painted and that there’s four million of them (more on that here), but this install bears an uncanny resemblance to Felix Gonzalez-Torres’s silver-candy piece, Untitled (Placebo), from 1991 — which is currently on view at MoMA. And which can be touched and eaten.
